What occurs when the active sites on
ACTIN are exposed?
During Relaxation,
What Triggers This Relaxation?
What Caused the Ca++ Ions To Be Depleted
Within the Sarcomere (thus causing relaxation)?
STRENGTH AND POWER
QUESTION
STRENGTH DEFINED
POWER DEFINED
OTHER ACTIVITIES REQUIRING A HIGH DEGREE
OF REPETITIVE MOVEMENTS OVER TIME
HOW DOES ONE COACH AND/OR DEVELOP POWER,
STRENGTH AND MUSCULAR ENDURANCE
WHAT RESEARCH SHOWS
CAN STRENGTH BE LOST AS QUICKLY?
SO WHAT ARE THE MECHANISMS CONTRIBUTING
TO STRENGTH GAINS
INHIBITORY IMPULSES
Training Possibly Decreases The Inhibitory
Impulses.
OTHER REASONS FOR STRENGTH GAINS
Hypertrophy Alone Does Not Account For
Increased Strength.
CONFLICTING EVIDENCE
MORE RECENT SPECULATIONS ON STRENGTH
PROCESS OF STRUCTURAL CHANGE
MOST WIDELY ACCEPTED THEORY FOR INCREASED
MASS

A Change In The # of Myofibrils Or # Of Muscle Fiber?
CAN MUSCLE FIBER TYPES CHANGE?
HOW DOES ONE INCREASE POWER?

WHY DO WE SEE INCREASED MUSCLE ENDURANCE
AS A RESULT OF STRENGTH GAINS?
